Make-A-Berm allows for spill containment to be installed around difficult to move equipment, spill-prone areas, or areas where a standard-shaped berm wont work. Vented Corner pieces are key to providing a full spill containment. These allow air to flow thru as forklift traffic and hand truck equipment is being used. The corner pieces are easily attached to the berm pieces with the use of vinyl cement. Non-absorbent modified PVC coated fabric provides a highly resistant barrier to contain oils, gasoline, acids and other liquids.
